My present invention hasreference to-a fram mg tool for carpenters use,and my primary object isthe provision of a tool for this purposewhichwill enable the carpenter to readily ascertain the lengths and cutsof common 7 jack, hip and other regular or irregular rafters withoutresorting to the employment of a steel or framing square.

"Anotherobjectistheprovlsion of a framwhichpis pivotally associatedwiththe handle through the medium of removable discs,

in-g tool that includesa handle and a blade which latter have inscribedthereon a protractor or degree scale as well as other marks ofgraduation designed to be brought into alinement with marks orgraduations arranged 'incir'cular relation on the handle of the tool,theprotractor or degree scale being disposed opposite a pointer 'mark onsaid handle; whereby the blade may be turned on the handle to arrangethese-parts at determined degrees or whereby the rise per inch and thedifferent angle of cuts of jack or other rafters may be obtained, theblade being suitablescaledto correspond with the scales on the discs andhandles. i

To the attainment of the foregoing and other objects which will presentthems lves as the nature of the invention is better understood, theimprovement also resides in certain other novel featuresof'constriiction, combination and operative association of parts, onesatisfactory embodimentof which is disclosed by the accompanyingdrawings.

' the numeral 1 designates the handle of the imprevement The handle is,preferably' widened on one end" th r bf hd, th end of the said handleis rounded but the same 1s prov ded with a lug extension 2. The

rounde'dporti-on or head oft-he handle may i be either integrallyformedor may 'providea separate element from-the remainder of thehandle. Byreferen'ce to Figure/l it will be seen that the inner edgeofth'e hand leifs widened outwardlyyas at This is to' permit of the saidedge of the handlemoi e ffirmly contacting with'the edge of a piece oflumber against which it is'arranged. -"lh'e handle, from its saidinnerand widened edge 3 is slotted longitudinally to provide the samewith a pocket 1, and the inner wall of -the pocket entering-the roundedend of the handle has its rearwall also rounded and l terminates in aline with thelu'g 2; The rounded end of the handleis provided with acentral opening 5. i i

The blade is broadlyindica-ted by-the numeral 65 the same'having itsedge at one-0f its corners formed with a rounded projection '7 that isdesigned to be received in the rounded portion of the pocket 4. Thestraight shoulder 18, provided at the end of theblade proper isdesigneditocontact with the'lug 2 to hold the blade at arightangl'e withrespect to the handle 1 whereby the-tool may be employed as a square; aI The rounded portion 7 of the bladed is providedw-ith a central opening9 and with l ing-in the secondside ofithe handle." There is passedthrough a central opening in the disc lathe opening 9in the blade 6 andthreaded in a centralopening'in the disc 14 a a screw or bolt member "15; the' di'sc 13 being reamed'around the opening-of the said screw orbolt so that the he'ad-ofthe saidscrew or I bolt is pocketed inthe'disc; "By adjusting the element 15 the discs 13 and 14 may-bebrought into frictional contact widethe opposite faces of the handle tocompress the same against the part 7 of the blade 6, and thereby sustainthe bladewhen swung at different angles on the handle. The reducedportions 12 and 15 of the respective discs are in the nature of hubs andcontact with the rounded or what may be termed the hub por tion of theblade. g I By reference to the drawings it will be noted that the disc14 is of a slightly less size than the disc 13 and that both the discshave their outer faces beveled from their edges.

The disc'14, from its said beveled edge is graduated, as at 16, and thesaid graduations in the showing of the drawings are numbered from 3 to16. and these figures are for the purpose of obtaining the side cuts ofjack rafters, the span in feet and the rise in inches of saidrafters'being inscribed by scales on the blade 6 as will hereinafter bedescribed.

' For the purpose of illustration we will suppose that in framing a hiproof on say an 8 and 12 pitch to obtain the side cut of the jackrafters, it is merely necessary to swing the blade and the disc to bringthe indicating mark 8 on the disc opposite the figure 8 on one of thecircular graduations 17 on the handle and thus obtain the proper angle.It should be stated that the principle in using my improvement is thesame asthat employed in the use of a steel square or a framing square.In addition to the circular graduations on the handle that surround thedisc 14 there are other annular series of graduations each suitablymarked, and whereby the side cuts of jacks difierently spaced may bereadily ascertained by simply swinging the blade as above mentioned.

The side of the handle illustrated in Figure 1 of the drawings has itsinner edge inscribed with spaced numerals to indicate plumb cuts andcorresponding seat cuts, and the outer edge of the blade 6 on the facethereof disclosed by Figure 1 of the drawings is pro vided with a'ruledscale 18 and inward of the ruled scale the blade has inscribedthereonnumerals 19 to indicate the span in feet of the jack 'or other rafters.Below the numerals 19 the blade is divided by longitudinal andtransverse lines into columns of figures to indicate the rise in inchesof the rafter according to the rise per inch in the run'of the rafter,and according to the width of the building. In the showing ofFigure 1the character .12 is arranged in the cenmr and a little above theabbreviations'for the common or for the hip rafters, and the character12 indicates that the building is v12 ft. wide, theother numerals in aline with the numeral 12 indicating other widths of buildings.

On the opposite side of the blade disclosed by Figure 2 the portionthereof nearest the handle is provided with a lumber measure ment scale20 and with figures indicating the span in feet of a building, columnsin which are inscribed figures indicating the rise in inches of commonand hip rafters, these scales being a continuation of the scales shownon the face of the blade in Figure 1. The disc 13 is shown on this faceof the scale, and the same has inscribed thereon a degree or pro tractorscale 21 whose markings are arranged to aline with an arrow or likeindicator 22 on the top portion of the handle 1. Approximatelydiametrically opposite the protractor or degree scale the disc 13 hasinscribed thereon a numbered scale 23 to indicate the side cut of hiprafters, the scale in the present instance 26 to indicate the seat cutof hip rafters. In

addition to this the face of the scale may have arranged or inscribedthereon discs, squares, etc., having angle lines marked thereon andindicia relative to the position at which the blade is to be turned onthe handle to obtain desired mitre cuts.

With my improvement the lengths and cuts of rafters in the framing of abuilding may be easily obtained by a carpenter who is unacquainted withthe use of a steel square and in a more expeditious manner. Theimprovement it will be noted provides a combined square, bevel andpr-otractor, and the simplicity and advantages of the construction will,it is thought, be fully understood and appreciated without furtherdetailed description. Of course, discs having different scales thanthose illustrated may be employed when different angle cuts arerequired, and as a matter-of-fact, I propose to commercialize theimprovement in a number of such styles and likewise with a book ofinstructions as to the use of the tool, it being understood that thedescription as herein set forth, merely is intended to convey certainpurposes and methods for accomplisl ing desired results by theemployment of the improvement.

It will be apparent that when the blade is foldedintothe handle the toolcan be easily carried in the pocket of the carpenter or convenientlystored-in his tool box.

The outer or headed end of the handle may and preferably has arrangedina socket therein a spring influenced headed latching bolt 28. Theinner end of the bolt is flared to a point, as indicated by the numeral29 and the said end of the bolt is designed to hereceived insubstantially V-shaped notches 30 in the periphery of therounded-portion 7 of the blade 6. The notches 30 are preferably sospaced that the blade will be held at a right angle with respect to thehandle when the locking dog is received in one of'the notches and thesaid blade 6 will be held at an angle -weenie of 45 degrees with respectto the handle when p the locking device is received in the second beprovided with additional notches.

notch. Obviously the end 7 of the blademay The locking bolt 28 passesthrough a central opening'bolt has a pin 35 that is received inthenotch. The spring 36 contacts with the bushing and also with a discenlargement or flange 37 on the locking bolt. It will be apparent thatthe. flange 37 will prevent the locking bolt from being entirelywithdrawn from the socket or opening therefor and it will be furtherapparent that by exerting an outward pullupon the headed end of thelocking bolt to bring the pin out of the notch in the bushing andthereafter turning the locking bolt to bring the pin away from thenotch, the

active end 29 of the bolt will be brought out of engagement with thenotches in the end 7 of the blade.

As disclosed by the drawings, the pivot bolt 15 has one of its endsengaged by a wing nut 39, the adjustment of which permits of readyswinging of the blade on the handle, and for likewise causing thebifurcated end of the handle to exert a frictional contact"throughithedlscs and through the saidextenwith the blade for holding thelatter from free turning on the pivot bolt 15. g I Having described theinvention, I claim 1.
